Would you be open to a PR changing from grid layout to flexbox layout?

Love the minimalist style, but it's bothering me that the content div is overflowing and creating a scrollbar. I've looked through the stylesheet a bit and played around, and I believe the cause is due to the way the grid layout is used (although I'm not 100% on this).

If you prefer to stay with the grid style, that's cool. I'll keep my forked version for my own usage.
